Question

which one has more nuclear charge among Na or CS ?why?​

Answer 1

Answer:

Cs

Explanation:

Answer 2

Because chlorine is in the same period as phosphorus and sodium, but has the most protons in its shell (the most right within the same period) it has the greatest effective nuclear charge. We're being asked to determine the subshell in the tin atom that experiences the lowest effective nuclear charge. Recall that the effective nuclear charge is the force exerted by the nucleus onto an electron. Electrons that are further away from the nucleus have a lower effective nuclear charge. Poor shielding means poor screening of nuclear charge. In other words, the nuclear charge is not effectively screened by the electrons in question. The shielding effect of different orbitals is as follows:​ s orbital's > p orbital's> d orbital's> f orbital's. Apr 20, 2018
